A modern earthquake rocked southwestern Greece last week, but there were no reports of damage or injuries. The 4.1magnitude quake occurred under the ocean, west of Athens.
A 4.2 magnitude quake hit Iran last week as well. No reports of damage or injuries have been reported there, either.
Recently, quakes have been felt in El Salvador and off an island in Japan. There have been minor quakes in Ohio and New York City.
Are more quakes coming? After one of the worst earthquakes in history hit India, killing over 100,000 people, many of usare quaking with fear about the future. Will the Big One finally hit Los Angeles, as forecasters have been predictingfor years?
About 18 major quakes-measuring from 7.0 and 7.9 on the Richter scale-and one Big One, measuring 8.0 or more, can beexpected every year. We don't hear about all of them, because many of them strike uninhabited areas of the world.
The current wave of quakes has started scientists speculating about whether or not they are related to one another. Recent earthquakes have occurred on separate tectonic plates, and a quake on one plate supposedly does not set up a domino effect on another.
The traditional view is that earthquakes are separate, unique events. "These earthquakes are not related," said WaverlyPerson, director of the Earthquake Information Center in Colorado. "We locate about 50 quakes every day. But you onlyhear about them if people are killed or if they're felt very strongly in the United States."
